At the very least for scientific surveys, additional works are needed to understand their emission and model their effects and then forecast the level of contamination/bias via simulation. Mitigation strategies might be needed, such as changing the scanning strategy. Masking out the point sources effectively reduces sensitivity, effectively losing money in the sense that they are either going to miss the target from initial funding, or need to ask for more funding. In short, all astronomers are affected, the more expensive programs are likely affected most as they often are targeting higher sensitivity (hence it will be sensitive to even small amount of contamination) and/or large fraction of the sky (hence it is impossible to avoid scanning across any of them).
